sb-database

sb-database is a skill for Claude Code, Codex from stablebaseline/mcp. It costs 148 tokens per session (3,660 once invoked), scanned A, original, MIT.

A database guide for Stable Baseline, covering tables of typed fields, views, row rules, and rows. It treats a database as a set of tables, much like sheets in a workbook, within a project, workspace, or organisation.

In plain words
What is it for?
Creating and inspecting databases, adding or changing tables and rows, importing small CSV files, answering questions about data, and exporting rows.
Why use it?
It removes the need to guess database identifiers, field types, access rules, or table structure before making changes. It also keeps reads and updates within the signed-in user's permitted rows.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sb-database scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Stable Baseline: databases

What this skill does

Makes and changes databases, shows them, answers questions about their rows, adds and changes rows in bulk, brings small data in from CSV and exports rows. A database holds tables of rows, like a workbook holds sheets. It lives in a project (a project holds one database), in a workspace (shown in every project of the workspace) or in the whole organisation. Every call runs under the signed in user's own Stable Baseline identity, and only rows the user may see are returned, counted or changed.

IDs are never hardcoded. Resolve projectId, workspaceId and databaseId at runtime from listing calls made in this conversation.

Before you start

  1. Resolve scope. listOrganisations, listWorkspaces, listProjects. Ask if several projects are accessible.
  2. Find the database. listDatabases with projectId (or workspaceId, or query to find one by name or friendly ID such as DB-12).
  3. Read the table before you use it. getDatabase with databaseId and table returns the fields with their exact names and types, the choices of each choice and status field, the views, the row rule and the user's access. Use those names exactly as returned.
  4. Learn a shape once, rather than guess it. getDatabaseGuide with a topic, such as overview, finding_rows, totals_and_groups, analytics, bulk_changes, fields_and_types, structure, views, importing, deleting, limits or errors. Without a topic it lists them all.

Databases on this connection. Databases have their own Read, Write and Delete on every connection, and they start unticked when Stable Baseline is connected. A connection can also be held to chosen databases and tables: one it does not reach answers as not found. If a tool says this connection is not allowed to read, change or delete databases, or is limited to some databases, say so in those words. The person can change it: connect Stable Baseline again, choose Reconfigure on Stable Baseline's screen, and tick the Databases row (Read to see, Write to add or change rows, Delete to delete), or choose databases under Scope to Databases.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
